| 摘 要： | The doping-induced spectral weight transfer is studied by using the d-p model and considering spatial fluctuations in the high-To cuprates. The results led by the Cu-O interaction are found as follows: (i) the energy levels are grown inside the charge-transfer gap, (ii) the spectral weight is decreased below EF, and Oil) the d holes at Cu-sites in CuO2 planes are delocalized with hole doping. Both metal-insulator transition and electrons of two states are also discussed.
